Crate libyaml 

High-level bindings for the LibYAML library.

Reading YAML

To read a YAML stream, use Parser. This example counts the number of alias events in a stream.

let alias_count = Parser::new(reader)?.into_iter().filter(|e| {
    if let Ok(Event::Alias { .. }) = e { true } else { false }
}).count();

Writing YAML

To write a YAML stream, use Emitter. This example writes a stream with a single document consisting of a single scalar.

let mut emitter = Emitter::new(writer)?;

emitter.emit(Event::StreamStart { encoding: None })?;
emitter.emit(Event::DocumentStart { implicit: true })?;
emitter.emit(Event::Scalar {
    anchor: None,
    tag: Some(tag::INT.to_string()),
    value: "42".to_string(),
    plain_implicit: false,
    quoted_implicit: false,
    style: None,
})?;
emitter.emit(Event::DocumentEnd { implicit: true })?;
emitter.emit(Event::StreamEnd)?;
